Predict the impact on blood pressure for a patient who hypersecretes adrenocorticotropic hormone (ACTH)
What will be an ideal response?
ACTH stimulates aldosterone production and release from zona glomerulosa of the adrenal cortex. Hypersecretion of aldosterone, or hyperaldosteronism, can lead to high blood pressure. Aldosterone promotes sodium and chloride ions reabsorption in the tubule cells of the kidneys. In turn, a concentration gradient favoring the movement of water by osmosis from the fluid in those tubules to the extracellular fluid and blood is created. When aldosterone indirectly promotes water reabsorption, extracellular fluid and blood volume are increased, which in turn increases blood pressure.
